Adi,
The reason we're attempting to add more nodes is trying to solve the
long/simultaneous compactions, i.e. the performance issue, not the storage
issue yet.
We have RF 5 and CL QUORUM for read and write, we have
size. Keep adjusting it until the frequency/size of
flushing becomes satisfactory and hopefully reduces the compaction overhead.

So, we're on 8, so I don't think there's a key cache setting. Am I wrong?
here's my newest crash log:

The seedlist of A is localhost.
Seedlist of B is localhost, A_ipaddr and
seedlist of C is localhost,B_ipaddr,A_ipaddr.
Using localhost(or own IP address for non-seed nodes) is not a good
practice.
Try
The seedlist of A : A_ipaddr.
Seedlist of B : A_ipaddr
seedlist of C : A_ipaddr
by setting it to 0.0.
Running nodetool repair will reduce the chance of inconsistent data, it does
not mean that read repair will not get triggered.

Need set memtable_troughput for cassandra
I try do this with help

make a Cassandra cluster way too costly , we would have to buy 16 systems

I have been going through the mailing list and compiling suggestions to
address the swapping due to mmap issue.
1) Use JNA (done but)
Are these steps also required:
- Start
I might be doing incorrectly either in schema
definition or the way I am sending the values are welcome.

That was it. Thanks thobbs :-) The queries work as expected now.

1) So if your node tokens are set as vertexid_ all keys with the same
prefix will be in the same range.
Adding to Aaron's comment -
This will be the case if you use OrderPreservingPartitioner.
RandomPartitioner(the default) will distribute the tokens randomly across
nodes.

the files a node should be having(say the ones
that show up in stream command) and just scp them to the new node.
Thank you for your time.

FYI Ended up re-starting the whole cluster which in effect decommissioned
the dead node and redistributed the data
of Operations wiki page. That actually led to a more unbalanced load
distribution (Which the doc warned can happen if the key distribution is not
even).
Any suggestions/pointers are welcome. Thanks.
